To all whom it may concern:

Be it known that I, ALFRED L. SAVAGE, Jr., a citizen of the UnitedStates, residing at New York, in the county of New York, State v of NewYork, have invented certain new and useful Improvements in Atomizers;and 1 do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in medicine applicators, andparticularly to sprayers or atomizers.

One object of the present invention is to provide a novel and improveddevice of this character which is simple in construction, easy ofoperation, and which will be strong and durable.

Another object is to provide an improved device of this characterwherein the air forced into the medicine container will be preventedfrom being sucked out again, as is the case with the use of the ordinaryrubher bulb.

()ther objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawing. f

In the accompanying drawing:

Figure 1 is a side elevation of an atomizer made in accordance with myinvention.

Fig. 2 is a vertical longitudinal sectional I view through thedevioe.

Fig. 3 is a rear elevation of the device.

Fig. 4 is a vertical transverse mctional view taken on the line Hot Fig.1.

Referring particularlyto the accompanying drawing, 10 represents a glassor other container for the liquid medicine to be sprayed or atomized. Ahollow cap '11 is screwed on the container, and from the upper end ofsaid cap there extends the pipe 12, having the nozzle 13 on the outerend, and through which the medicated air is dis-' charged, in a finespray. Disposed through the pipe 12, and down into the medicine in thecontainer, is asmaller pipe 14 through Specification of Letters Patent.Application filed Apri120, me. Serial no. ceases.

Patented Feb. is, rate.

which the liquid medicine is drawn by the air in the pipe 12, and withwhich it is mixed and discharged through the nozzle in a fine spray.Secured to one side of the cap 11 by means of the nipple 15, is a hollowcylinder 16, in which is disposed'a plunger or piston including themetal disk 17,

the leather washer 18, and the plunger rod 19, which latter extendsthrough the other end of the cylinder. The said rear end of the. pistonor plunger rod is provided with a finger button 20, and encircling thesaid rod, between the end cap 21, of the cylinder,

and the said button, is a coil spring 22,

which yieldably holds and normally returns the piston to its outermostposition in the cylinder. A depending loop member 23 is secured'to thelower side of the cylinder and has one of its arms secured to the cap ofthe container, whereby the cylinder will be properly and stronglysupported on the cap. This loop member also serves to assist the person'in holding the atomizer, the thumb of the hand being passed throughsaid loop,

while the first and second fingers of the hand press 'inwardly.on thebutton of the plunger rod. Immediately upon the release of the plungerrod, the spring 22 restores the plunger to its normal outer osition.

llt will be noted that formed with an enlarged portion 24 in which isformed avalve seat 25 for the valve 25. This valve moves into closedposition,

toward the adjacent end, of the cylinder, whereby the back pressure ofthe air forced into the cap by the piston will be prevented fromreturning into the cylinder. Thus the air which is forced into the capbythe piston, will completely discharge itself through the nozzle drawinga portion of the liquid e nipple 15 is from the container andformingwith said liquid, a fine spray.

With a device'of this character and construction, the undesirablefeature of the air being sucked from the container, when the bulb isreleased, is obviated, and greater efficiency in the atomizing of theliquid produced. Furthermore, the fact that the air fercing device isformed or metal is cenducive to greater strength and greziterdurability.

mat is claimed is:

.An atomizer including a receptacle for liquid medicament, a hollow capon the receptacle, an atomizing nozzle connected to the cap, a cylindermounted on the cap and having a spring returned piston, a handle memberconnecting the cylinder and cap,

nipple between the cylinder and cap, and an outwardly closing valve insaid nipple whereby the cempressed air forced through the cap by thepiston into the receptacle is prevented from return into the cylinder.
